They’re both environmentalists; passionately fighting for reduction in use of fossil fuels

They’re both creating space-travel businesses based on rockets that burn more fossil-fuel-per-customer than any other type of commercial vehicle ever devised

They both want to colonize mars because Earth may be doomed

They both have bumped uglies with Cameron Diaz

All of the above (except D, maybe)

The answer is…. E. Yes, I know E sounds impossible, because how can a person of obvious intelligence think of himself as an environmentalist while at the same time be building businesses based on burning huge amounts of fossil fuels?Holding two contradictory beliefs at the same time is known as cognitive dissonance.In most people cognitive dissonance causes severe mental stress. What is special about these brilliant entrepreneurial minds that let’s them hold such diametrically opposing views without breaking?Richard BransonRichard Branson cares a lot about the environment of our planet. As an environmentalist, he created the $25million earth challenge for greenhouse gas removal. As an environmentalist, he launched a green energy plan for the Caribbean. As an environmentalist, he has pledged billions to fight global warming.But there’s another Richard Branson: Richard Branson the anti-environmentalist. As an anti-environmentalist, he has built airlines (Virgin Atlantic, Virgin America, and Virgin Australia) that burn about 1/4 of a billion gallons of fuel every year. As an anti-environmentalist, he has built Virgin Galactic, with the goal of giving rich douchebags two hours in space at a monetary cost of $200,000 per person, and an environmental cost of 5 tons of CO2 per passenger (this is to be followed by space hotels, and eventually flights to colonize Mars at an environmental cost of a jabillion gallons of fuel per trip). As an anti-environmentalist, he owns his own island on which he entertains politicians, business tycoons, and celebrities who he flies in on private jets for fun-filled cerebral meetings at which they discuss plans for a sustainable world.How do these two Richard Branson’s live peacefully in the same body among such cognitive dissonance? How does he not wake up every night screaming to himself “My God, I’m such a fucking hypocrite?”By many accounts, Richard Branson is just bat-shit crazy, and so his secret may be simple insanity. That’s the only way I can understand the cognitive dissonance of Richard Branson: that he’s just crazy.Elon MuskI have a harder time simply calling Elon Musk crazy. He’s too much of a personal hero to be dismissed so easily. And yet Musk also supports two diametrically opposing goals: On the one hand he sincerely wants to make a car that can be sustainably fueled; on the other hand he sincerely wants to make passenger space travel cheaper and to even fly people to colonize Mars.How does Elon Musk reconcile this cognitive dissonance? By creating two separate companies. One Elon Musk runs Tesla, working hard to transport humanity across the land without burning non-renewable fuel. The other Elon Musk runs SpaceX, working just as hard to make it easier for more people to burn more fuel more frequently to travel into space.The only way these two Elon Musks can get along, without constant bickering and self-hatred, is by working at separate companies where the two Elons never meet, never work together, and never have to talk to one another. It’s a very clever solution to a nearly-intractable problem, as you’d expect from a very clever man.Can the virtues of Tesla offset the sins of SpaceX?I wonder… Given the stupendous amount of energy use to launch a passenger for a ride in a SpaceX rocket, can even the most efficient Tesla car save enough fuel to compensate for that one SpaceX ride?It takes a huge amount of energy to launch stuff into space, huge amounts–remember, you’ve got to push a weight, along with the weight of its fuel (which, for the shuttles, was 240 times the weight of the object itself), to 25,000 mph against gravity and with nothing to push against except Newton’s second law. Back when I was a young physics student I could have worked out some numbers quickly but now I just do web searches and find other’s estimates, which, in summary, come down to “huge mind-blowing amounts of energy”.Using just a few optimistic numbers from Musk and SpaceX (who are trying to greatly reduce costs) we see that their Falcon 98 launch uses 30,000 gallons of kerosene and 40,000 gallons of liquid oxygen. That’s a huge amount of fuel. (How much fuel does it take to make 40,000 gallons of liquid oxygen? I don’t know, but I wager it’s a huge amount.)SpaceX launch costs are currently at $1,862/lb (which I assume are mostly energy costs). Musk has said he wants to get that down to $500/lb. He’s a real smart guy, so maybe he can figure out how to achieve that, but even so that represents a huge amount of energy just to achieve orbit (that’s equivalent to the energy of something like 25,000 gallons of gas to put a single 200 lb person into orbit—start dieting guys!).Compare: UPS will fly stuff around the world for about $10/lb (I’ve seen estimates for a few dollars per pound). A cargo ship can float stuff around the world for pennies per pound. Or we can push stuff to space for $500/lb (hopefully, someday, if they’re right about being able to bring costs down).

Question: If I replace my gas-driven car with a Tesla to save fuel, how long before I have saved enough fuel to make up for pushing my 190 pounds into space just one time?Answer: Using Elon Musk’s most optimistic numbers, you’ll have to drive a Tesla for about 120 years to save up enough fuel for one spot on a SpaceX launch.

A conversation between parent and child, on Mars, sometime in the future:Parent: See that little blue dot in the night sky? That’s Earth.Child: What is Earth?Parent: Earth was the planet of our ancestors, before people came to Mars.Child: Who lives on Earth now?Parent: Nobody. It’s a dead planet. The actions of rich, selfish people destroyed it.Child: How did the rich, selfish people destroy Earth?Parent: They burned it up as fuel, getting to Mars.

A final, private message for Richard Branson and Elon MuskEverybody except for Richard and Elon, you can go away now. This last part is only for the two of them. So, bye bye, everybody else.

Dear Richard and Elon,If you really care about the environment, then please stay on the ground. Please accept the limitations of known physics and chemistry, and understand that we are a long long way from any breakthroughs that will lead to a sustainable way to fling people into space. Sorry, but it’s true: there is no current way to be both an environmentalist and a space traveler. You’re just going to have to redirect your rocket-science level of brilliance to improving the planet we’re on.

Elon, you can go away now. This last part is only for Richard. So, bye bye, Elon.

Richard, now that we’re alone, I know what you’re thinking: “We'll offset the carbon footprint of our rocket launches by creating a new business, Virgin Forest, to plant trees on the moon.” No, Richard, that’s just stupid.

Animinimalianism: the practice of minimizing, although not abstaining from, the consumption of meat – red meat, poultry, seafood, and the flesh of any other animal – by favoring a small part of a large animal over a large part of a small animal, out of respect for the equal worthiness of all sentient life.

a teaching moment from a sad plate o’ shrimpMy transcending moment of dietary enlightenment struck while I was staring down a surprisingly large plate of surprisingly small shrimp. “There must be two hundred shrimp there,” I thought. “Two hundred shrimp have given their lives for this meal.” I suddenly felt very sad.I was about to discover animinimalianism.the path from omnivore, to vegetarian, to pescetarianEating meat is kind of disturbing, if you stop to think about it. I did not stop to think about it for the first 20 years of my life. I just ate in ignorant bliss. Nom nom nom nom nom.Then I did think about it, and I came to the realization that meat was murder, pain, suffering, and so on. I became a vegetarian.As a vegetarian, my conscience felt better, but after a few years I realized that my body did not “feel better”. I simply felt better when I ate some animal protein and animal fat.So I tried pescetarianism, where I wouldn’t eat fish except for fish. And later on I added some chicken because of the whole “it doesn’t have a face” thing.egotistical dietary ethicsBut staring at that plate of shrimp–imagining little shrimp faces on those little shrimp bodies–it struck me as ridiculous to base the value, joy, and pain of a life or death on how much a creature’s face happens to look like mine, or whether it happens to lactate like my species, or how far away it is on the evolutionary tree. To think that I could say which life was more recipe-worthy than another seemed, if not racist, at least speciesist, or phylumist, or something-ist.As the great philosopher, Horton the Elephant, once nearly said, “a life is a life, no matter how small.”If you’re going to be a vegetarian and eat no meat, then good on you. But if you are going to accept that you’re an omnivore, don’t be so egotistic as to believe that an animal’s worthiness depends on how close it is to you in appearance or sentience.animinimalianismSo here’s my new thing: I’m not ready to eat no meat at all, but I do want to minimize the number of lives sacrificed to feed me. So I have become an animinimalian (from the root words “animal” and “minimal”): a practicer of animinimalianism.As an animinimalian I try to minimize the number of animals that die to make my meal. That plate of shrimp, for example, sacrificed two hundred lives; a trout might be 1 life; but a quarter pounder takes only about 1/6000th of a cow’s life; so I order the quarter pounder.A chicken plate might take 1/4th of a life; but a blue-whale patty kills only 1/400,000th of a blue whale; so go with the whale. (Another reason to eat blue whales: they feed on krill, millions of them daily, and so blue whales are terrible animinimalians and so just might deserve to be eaten.)final ethical dietary warningI realize that while the above rationale for everyone practicing animinimalianism makes 100% absolute perfect rational logical sense, there are some blasphemers who might twist this logic into saying that it’s OK to eat people.Let me make this clear: It is NOT OK to eat people. Not even fat people. Cannibaminimalianism is NOT OK!!!Bon appétit.
